PUMP.

SPECIFICATION forming part of Letters Patent No. 285,093, dated September 18, 1883.

Application filed February 19, 1883. (No model.)

To all whom it may concern:

Be it known that I, J OI-IN WOGK, a citizen of the United States, residing at Canton, in

'the county of Stark and State of Ohio, have invented certain new and useful Improvements in Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

Figurel is a vertical section taken centrally of the two cylinders of my pump, and Fig. 2 is a side elevation taken at right angles to the view shown in Fig. l.

The object of my invention is to produce a simple, durable pump with which a prac-' ticallycontinuous stream of water can be thrown.

A is a cylinder or working-barrel having an interior bore of uniform diameter nearly or quite its entire length, and provided near its top and bottom with projecting connecting pipes or ducts B B.

a is, a valve near the lower end of cylinder A, opening upward.

' O is an extension'foot-piece of the barrel A, and secured to the lower end thereof by a threaded thimble, c, or any equivalent therefor, the foot-piece being perforated or otherwise so constructed as'to admit a free passage of water through it to the valve a.

D is a piston-rod working through a stuffing-box, d, which is attached to the upper end of cylinder A.

E is a piston attached to the lower end of the piston-rod, and consists by preference of a solid block of either metal or wood.

' One of the objects of the invention is to allow some of the water drawn into the working-barrel to pass from one side of the piston to the other. This is attained, preferably, by so constructing the piston itself as that it shall allow the passage of the water directly from 1 H is a knee-rest projecting from the cylin= ders, and by preference connected to both of them, and further supported by braces 71, which extend from the outer ends of the kneerest to the cylinders.

This pump may be operated as follows: The piston being moved up and down, water will be drawn into the barrel A on the upstrokes, and on the downstrokes a portion of the water will be forced through the lower valve, 1), another portion of the water passing up around the piston, until, after a few strokes of the piston have been made, the cylinder A will be entirely filled with water, so that at each upstroke a portion of it will be forced through the upper tube, B, and into the cylinder F, and out through the discharge-pipe I. Thus at each up and down stroke water will be delivered through the discharge-pipe, and as the extreme upper end of cylinder F may be made to serve as an air-chamber a prac-.

tically-continuous stream-will be discharged through the hose J, the same as through an ordinary double-acting force-pump.

In making this pump for use in watering gardens or similar purposes, where but very little power is required, I' propose to make the cylinders and connecting-pipes of sheet metal, and solder or braze; but I do not wish to be limited to any specific mode of manufacture, nor do I wish to be limited to having or the other of said ducts, other portions of the water can move through the passage-way from one side of the piston to the other.

What I- claim is 1. The combination of the piston, the working-barrel having a single water-entrance only on one side of the piston, the receiving-chamher, the two ducts between the working-barrel and the receiving-chamber, and a per1na nently-open passageway from the lower side of the piston to the upper, through which some of the water can pass when the piston is forced downward.

2. The combination of the working-barrel and the receiver, having two ducts leading from the working-barrel to the receiver, each having a Valve, with the piston constructed to allow a passage by which some of the water can pass directly from thelower side of the piston to the upper, substantially as set forth.

3. In a force-pump, a cylinder having an induction-valve at its lower end and dischargeopenings near its upper and lower ends, in combination with a piston of less diameter than the cylinder, and arranged to traverse the space between the discharge-openings, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
